Detector Laboratory: The Mission  Helsinki Detector Laboratory offers premises, equipment and know- how for the execution of HIP experimental in-kind activities .  Detector Laboratory is a permanent infrastructure of Helsinki Institute of Physics (HIP) and University of Helsinki / Department of Physics (UH/Physics) with three main tasks: 1. Support the Finnish instrumentation of particle and nuclear physics experiments, such as CERN and FAIR 2. Support the education of experimental particle physics 3. Participate in externally funded R&D projects Eija Tuominen / IKBest5 9.4.2019 3

Detector Laboratory: The Team  Permanent laboratory staff: • Chief engineer: Doc. Eija Tuominen • Laboratory engineers: Mr. Jouni Heino, Ms. Pirkitta Koponen, Dr. Francisco Garcia • Laboratory technician: Mr. Raimo Turpeinen  ~20 research scientists and students  Collaboration with universities, institutes and companies (e.g. Jyväskylä, Lappeenranta, Aalto, STUK, Micronova, CERN RD50 and RD51) Eija Tuominen / IKBest5 9.4.2019 4

ALICE optical QA History of HIP IK  HIP / Detector Laboratory has provided in-kind contributions to CERN since 1980's (LEP-DELPHI Hadron Calorimeter). TAB bonding of 715 Silicon Manufacture of 700 Quality Assurance of Assembly of 50 GEM Strip Detector (SSD) carbon-fiber support 250 silicon pixel (Gas Electron modules for ALICE Tracker, structures for CMS detectors for CMS Multiplier) detectors 2004-2006. Tracker, 2004-2005. Tracker Upgrade, for TOTEM, 2008- 2014-2016. 2011. Eija Tuominen / IKBest5 9.4.2019 5

ALICE optical QA ALICE In-Kind: Our Task  In 2014-2018, Detector Laboratory hosted in-kind contribution to CERN ALICE Upgrade.  The project was coordinated by University of Jyväskylä / prof. Jan Rak.  The task: optical and electrical Quality Assurance of 360 GEM (Gas Electron Multiplier) foils for the readout of the ALICE TPC (Time Projection Chamber) detector – half of the total GEMs. Eija Tuominen / IKBest5 9.4.2019 6 Photo: CERN

ALICE optical QA ALICE In-Kind: What we needed #1 1. Research on GEMs - continuously: • R&D to predict GEM foil gain uniformity from geometrical hole properties obtained with high definition optical scanning system. Simulation by Dr. Timo Hilden Eija Tuominen / IKBest5 9.4.2019 7

ALICE optical QA ALICE In-Kind: What we needed #2 2. Infrastructure – sophisticated & unique • Properly maintained clean rooms and other laboratories . • Unique equipment for the optical and electrical QA needed to be designed, constructed and commissioned (bearing in mind EU, Finnish & University purchasing rules). 8

ALICE optical QA ALICE In-Kind: What we needed #3 3. People – plenty & skillful • Laboratory staff to maintain infrastructure & organize logistics. • Project scientists to coordinate activities. • Academically educated technicians to do the QA. • Doctoral students to participate in service work. 9

ALICE optical QA ALICE In-Kind: What we needed #4 4. Money – a lot of it • National funding agency, Academy of Finland , supported the in-kind contribution during 2014-2017 with two consequent FIRI (Funding Instrument for Research Infrastructures) projects. • The price tag of the in-kind contribution including specific equipment and technical people - not lab staff, students or premises: ~1 M€.

ALICE optical QA ALICE In-Kind: What next  GEM foils will be installed to ALICE TPC detector.  Helsinki Detector Laboratory has proceeded to CERN CMS & TOTEM in-kind contribution - & later to FAIR in-kind contribution. Eija Tuominen / IKBest5 9.4.2019 Photos: CERN 11

ALICE optical QA ALICE In-Kind: Lesson Learned 1. Positive: Yes we can! 2. Negative: There is always something unexpected (especially with the timetables). 3. Lesson learned: Do not underestimate the logistics. 4. Stress-saving: “Well planned is half done” – but prepare top improvise.. Our dream team: Dr. Erik Brucken, lab.eng. Pirkitta Koponen, lab.eng. Jouni Heino, student Tiina Naaranoja, technician 5. Learning objective for IKB5: “Together we are strong” - Essi Kangasaho, student Tomas Snellman, let us learn from each others’ experiences.
